| 摘 要： | 研究了烤烟旺长期的需水特点 ,结果表明 ,烤烟旺长期最佳土壤相对含水量应保持在 75 %～ 85 % ,在此土壤水分范围内 ,烟株对水分的利用效率最高 ,烟叶气水与外界的气体和水分交换最为通畅 ,而且根系的生长、茎的增高以及叶面积的增大方面都优于其它土壤水分环境中的烟株。

| Abstract: | Regular water requirement of flue\|cured tobacco at fast growing stage was studied. The results showed that the optimum relative water content was in a range of 75%-85% of the mass of soil, in which water\|utilization efficiency of tobacco plant was the highest, CO\-2 and moisture exchange between stomata of tobacco leaves and ambient air was the easiest, and the growth of root, stalk, and leaf of tobacco plant was the fastest. |

| Keywords: | Flue\|cured tobacco Water stress Photosynthesis rate Water\|utilization efficiency Relative water content |
